Win DataGrid Set a column to run a function?

In a web-data-grid I can get the builder to do what I want with respect to add a button as a column and dispaly the "part #" as the button text.

I have a ds bound to the grid already, I just need to enhance the first column to do more. I'd like to use a button to call a separae form (configurator or builder as an example). I'd need to pass the button text or a key in the call.
